3.A.1.5.45Uncharacterized 5 component peptide uptake transporter with a receptor, two transmembrane proteins and two ATPases, as is common for this family of ABC porters. The five genes encoding this system, from metagenomic data for an uncultured Lokiarchaeon, occur adjacent to each other in the genome (Zaremba-Niedzwiedzka et al. 2017).
